"In Cholette's compelling middle grade novel, Nick and Lily miss Dad, who left home a year ago for a construction project in New York. "He was the best digger around," Nick says, "operating big backhoes." To impress Dad, Nick dug a tunnel from his basement bedroom to the 50-foot-deep ravine behind their neighborhood; Mom, meanwhile, is too overwhelmed with work and single parenting to notice. When a climate catastrophe hits, Nick reveals his underground dugout, and the family hides food there...The fast-paced story includes social-issue themes, including bullying, mental health, and gun violence. Ortu's crisp illustrations individuate Cholette's diverse cast of characters and enhance her storytelling. Young readers will find this a (pun intended) breathtaking, page-turning read." --ALA  Booklist (Starred Review)
